A 2-D imaging heat-flux gauge

Description: This report describes a new leadless two-dimensional imaging optical heat-flux gauge. The gauge is made by depositing arrays of thermorgraphic-phosphor (TP) spots onto the faces of a polymethylpentene is insulator. In the first section of the report, we describe several gauge configurations and their prototype realizations. A satisfactory configuration is an array of right triangles on each face that overlay to form squares when the gauge is viewed normal to the surface. The next section of the… more

Progress report No. 31 for a program of thermoelectric generator testing and RTG degradation mechanisms evaluation

Description: Thermal conductivity measurements of the p-type and n-type selenide alloys after 19,800 hours and 6,500 hours, respectively, continue to show good agreement with the 3M Co. published data. Ingradient testing of n-legs after 8900 hours show comparable performance to the reported 3M data. Ingradient testing of p-legs at accelerated test conditions has completed 5432 hours and performance shows reasonable correlation with accelerated temperature and current gradients. This test has been discontinu… more

Separations of yttrium and some rare earths by liquid-liquid extraction

Description: The use of liquid-liquid extraction for the separation of some inorganic compounds was demonstrated. The yttrium-- rare earth concentrates were obtained from Fergusonite ore, Gadolinite ore, and a by-product from an ion-exchange resin separation process. In each case the mixture in terms of oxide was composed of from 50 to 60% yttrium and 5 to 15% heavy rare earths with the light rare earth fraction constituting the remaining material. Tributyl phosphate was generally employed for exracting nit… more
